The Effectiveness of Neuro-linguistic Programming Intervention in Enhancing Breast Milk Production, Reducing Stress Levels, and Improving Emotional Wellbeing among Breastfeeding Mothers: Quasi-experimental Study.

Background: Breastfeeding is essential for infant health, yet many mothers face difficulties in milk production, often linked to psychological stress. Neuro-Linguistic Programming (NLP) is a psychological method that may improve emotional wellbeing and lactation outcomes.

Materials and methods: A quasi-experimental study was conducted in Sorong, Southwest Papua (March-April 2024), involving 70 breastfeeding mothers with infants aged 0-6 months. Participants were randomly assigned to an intervention group (n = 35), which received a 4-week NLP program, or a control group (n = 35), which received standard breastfeeding education. Each NLP session lasted 60 minutes weekly. Outcomes included daily breast milk volume (measured with calibrated cups), stress (Perceived Stress Scale, PSS), and emotional wellbeing (maternal self-confidence, emotion regulation, and marital satisfaction). Assessments were conducted at baseline, immediately post intervention, and 1 month later.

Results: The intervention group showed a significant increase in milk production (from 450 ml to 600 ml/day; p < 0.05), while the control group remained stable. Stress scores declined in the intervention group (PSS: 22.4 to 14.5), with minimal change in the control group. Emotional wellbeing improved significantly across all domains in the intervention group compared to controls (p < 0.05).

Conclusions: NLP significantly enhances emotional wellbeing and milk production among breastfeeding mothers. These findings support incorporating NLP-based psychological strategies into maternal health programs, particularly in high-stress or low-resource settings. Further research with larger and more diverse populations is recommended.
